We’re looking for a skilled freelancer to set up Google Tag Manager (GTM) on our landing page and integrate it with Meta Pixel, as well as connect and configure analytics tracking for our Flutter mobile app (iOS & Android). The setup should include all essential events (page views, sign-ups, leads, add-to-cart, checkout, and purchases and etc) with correct parameter mapping for both GA4 and Meta Pixel. On the web, GTM should be fully implemented with consent mode and all tags firing correctly. For the mobile app, GA4 should be configured via Firebase Analytics, and Meta App Events should be integrated properly. The freelancer should provide a short handover document (2–5 pages) explaining how the implementation was done, how to add new events in the future, and how to test or debug them. Deliverables include a working setup across web and app, screenshots from DebugView and Meta Test Events for validation, and exportable GTM container files. Experience with GTM, GA4, Firebase, Meta Pixel, and analytics setup for Flutter apps is required. Bonus if you can set up server-side tagging (GTM + Meta CAPI). Please include examples of similar projects you’ve completed recently in your proposal. | Firebase and Meta accounts are ready and we want phase 1
